Example, so describing fairly simple, related part illustrates referring to the part of system embodiment.Method described below is implemented
Example is only schematical.
Specific embodiment two
As shown in Fig. 2, an embodiment of the present invention provides the GNSS PCBA automatic tests system in a kind of specific embodiment two
The application process of system, comprises the following steps.
Step S1, RS232 Serial Port Lines are first connected before starting shooting, and opens upper computer software on computers and clicks on operation and open
Beginning test software.
Step S2, by the system that is loaded with and the TF card groove of TF card insertion frock clamp for testing firmware.During test, PCBA
CPU on plate, which reads the test program in TF card in the memory on PCBA databases, to be run.
Step S3, battery main switch is opened, checks the total voltage electric current in upper computer software whether in allowed band at this time
Within.If it is next step S4 can be jumped directly to.If exceeding or falling below input voltage, illustrate on frock clamp
Power module is problematic, it is necessary to the problem of progress investigation.Meanwhile charactron is provided with the panel of frock clamp, for showing
The supply voltage and electric current of the power module, facilitate tester more intuitively to be judged.
Step S4, starting key, each PCBA databases is set to need to start shooting by touch-switch before powering in frock clamp.
Step S5, after starting shooting, upper computer software can gather the voltage and current of power supply by voltage and current capture card interface board,
Judge whether the voltage and current value of power supply within allowed band and obtains a result again.Surveyed if not within allowed band
Examination stops, and power supply automatically powers off.PCBA databases need to repair true there may be short circuit or other problems through technical staff
Second of detection can be carried out after recognizing.
Step S6, after normal boot-strap, the speech chip normal work on PCBA databases, drives the loudspeaker on frock clamp
Play startup music.Whether the phonetic function that the step is used to detect on database is normal.
Step S7, after completing above step, tester is by clicking on " functional test " button on upper computer software
Start other functions to PCBA databases to test.
Step S8, functional test is broadly divided into 3 major parts, including module voltage testing current, GNSS index tests, module
Communication test.
A) module voltage testing current：The supply voltage and electric current of modules on main test PCBA databases.
In the design of PCBA databases, modules voltage individually controls and the test point of 1mm can be designed at control source output.Survey
Pilot is connected by testing thimble with voltage and current capture card pinboard.NI PCI-6220 in PC machine are gathered by pinboard
Voltage and current information, and be shown in upper computer software.Upper computer software is by comparing the permission voltage electricity that designer provides
Flow valuve and actual measured value, draw test result.In upper computer software, with allowing the conclusion that is consistent of voltage and current can be with
Green, which is shown, simultaneously prompts PASS, with allowing voltage and current incongruent conclusion that is consistent with red display and can prompt FAIL.
Tester can whether each module voltage of PCBA databases be normal according to color intuitive judgment, and to abnormal PCBA data
Plate respective modules make a record, and facilitate maintenance personal to repair.
B) GNSS index tests.The test is tested for the important and critical functionality of PCBA databases, need to pay special attention to this
The test result of step.GNSS index tests can include test GPS L1, GPS L2, B1, B2, B3, GLN L1, GLN L2 tri-
Satellite data, signal-to-noise ratio and the precision of 7 frequency ranges of star system；Satellite data can include usable satellite number, and signal-to-noise ratio can wrap
